SQzyme PSL is a high concentrated Acid Protease derived from refined Aspergillus niger through cultivation and submerged fermentation technique.
SQzyme PSL hydrolyzes proteins efficiently under low pH conditions. Used in ethanol/alcohol production, it improves ethanol fermentation rates and increase ethanol yield for corn, milo or wheat based substrates. It provides more essential yeast nutrients by hydrolyzing gross protein into amino acids, peptides and free amino nitrogen.
》High ethanol fermentation rates and yield at industrial scale
》Yeast nutrients improvement
》Highly concentrated, less dosage
》Working under low pH suitable in fuel ethanol production
》Perfectly Coordinate with SQzyme AGL
Working pH range 2.5-5.0, optimum 3.0-3.7; Temperature range 30-50°C ,favorable at 40-47°C
0.10-0.20kg of SQzyme PSL (100,000u/mL) per ton of dry starch material.
(Dosage optimization should be performed based on individual plant.)
